Default 6.9l turbo idi international harvester
i am not really sure this is the correct place to seek suggestions and such for a cam for a turbo diesel.

i have said engine in a truck i am working on and i would like to get a cam that will help the turbo while maintaining low end torque. this engine only has three cams available for it stock, a regrind, and one cam made for high end (turbo) power.
the stock engine was never designed to have a turbo on it so the cam that is in it is probably not the most efficient things in the world for a turbocharged engine.

my goal is to have a good street/off road truck that gets good fuel mileage and has about 300 to 400 hp. i plan on running up to 30 psi boost, but for now will limit to 20 psi due to gasket restrictions. i would like a broad power-band making plenty of low end torque.

i don't know how much different a turbo diesel and a turbo gasoline cam would be.

You might want to try asking this question in the COMP Cams Product Support forum at You should get more response there.
